“…While both the migration routes and the final destinations have been documented with ringing studies and satellite transmitters (Klaassen et al 2012), the details of flight strategies and time-budgets of migrants are still largely unknown. Figure 3a shows the migration routes and movements during the wintering season of a male Lesser Black-backed Gull (ring MAMM, Id317) over 2 sequential years.…”

Tracking devices and bio-loggers provide crucial information on the ecology and behaviour of birds in their natural environment. An optimal tracking system should be lightweight, measure three-dimensional locations, enable flexible measurement schemes, transmit data remotely and measure environmental variables and biological parameters of the individual. Giving full consideration to the traits of birds and the constraints of technology, we have developed a GPS tracking system that attempts to achieve most of the aspirations of an optimal tracking system for free ranging birds without the need to recapture them. Here, we describe the design, performance and limitations of the system. We also present measurements on the tracked Lesser Black-backed Gull Larus fuscus to show how such a system can generate new opportunities for research at multiple scales. The GPS tracker weighs 12 g and includes a GPS receiver, micro-processor, 4 MB of memory for data storage, solar panel and battery. It has a tri-axial accelerometer to monitor behaviour. To maximize flexibility, it is equipped with a radio transceiver for bidirectional communication with a ground-based antenna network, which enables data to be downloaded and new measurement schemes to be uploaded remotely. The system facilitates a multi-scale approach to studying bird movement, from fine-scale movements (3-s measurement intervals) to long-distance migratory movements (intervals of 20-30 min) of the same individual. We anticipate that flexible tracking systems that enable researchers to optimize their measurement protocols will contribute to revolutionizing research on animal behaviour and ecology in the next decade.

“…Such behaviour is consistent with observations of Lesser Black-backed gulls made in the field and known behaviour for Lesser Black-backed gulls (Davis and Dunn 1976). Lesser Black-backed gulls are known to be pelagic with frequent trips to the open sea for foraging (Klaassen et al 2012;ShamounBaranes et al 2011). There is movement towards the feeding grounds during the early morning and evening hours followed by prolonged periods of roosting.…”

“…During the postbreeding period, seabirds use various dispersal and staging strategies to build energy reserves for migration (Huettmann and Diamond 2000, Klaassen et al 2012. High-quality staging areas provide sufficient space for roosting aggregations, abundant prey, and minimal disturbance by humans and predators (Warnock 2010).…”

ABSTRACT. In the western North Atlantic, Common (Sterna hirundo) and Arctic (S. paradisaea) Terns are sympatric at breeding colonies but show divergent migration strategies to coastal areas of South America and pelagic regions of the Antarctic, respectively. During 2013, we studied postbreeding movements of adult Common (n = 130) and Arctic (n = 52) Terns from four breeding colonies in the eastern USA and Canada using digital very high frequency (VHF) transmitters and an array of 62 automated radio telemetry towers. Relative to hatch dates at respective colonies, Arctic Terns departed breeding sites an average of eight days later than Common Terns. Common Terns were detected during the postbreeding period by coastal towers upward of 850 km south of their original nesting sites. The telemetry array detected postbreeding movements of Arctic Terns from the Petit Manan Island colony in the Gulf of Maine as they traveled eastward past Nova Scotia, Canada, mostly during the night. Nantucket Sound, Massachusetts, USA was identified as an important staging area for Common Terns from all colonies, whereby 26% of 53 tagged Common Terns from colonies in the Gulf of Maine and Canada were detected for up to three weeks. Common Terns typically arrived at Nantucket Sound within 2 h of sunset, 2 to 10 days after their last detection at Gulf of Maine and Canadian colonies, suggesting rapid postbreeding dispersal. Postbreeding dispersal of Arctic Terns was poorly documented with the telemetry array, suggesting that this species is not using coastal sites for staging, and is instead departing directly from colonies to offshore staging areas prior to long-distance migrations. We conclude that digital VHF telemetry is a useful method for monitoring regional movements of Common Terns, but additional offshore receiving stations are needed to effectively monitor movements of Arctic Terns away from their nesting colonies. Le réseau de télémétrie a détecté les déplacements postnuptiaux de Sternes arctiques de leur colonie de l'île Petit Manan, dans le golfe du Maine, au moment où elles se déplaçaient vers l'est au large de la Nouvelle-Écosse, Canada, le plus souvent durant la nuit. Le détroit de Nantucket, Massachusetts, É.-U., a été identifié comme halte migratoire importante pour les Sternes pierregarins en provenance de chaque colonie : 26 % des 53 Sternes pierregarins suivies dans les colonies du golfe du Maine et du Canada y ont été détectées pour une période allant jusqu'à 3 semaines. Les Sternes pierregarins arrivaient généralement dans le détroit de Nantucket dans les deux heures précédant le coucher du soleil, de 2 à 10 jours après leur dernière détection aux colonies du golfe du Maine et du Canada, indiquant une dispersion postnuptiale rapide. La dispersion postnuptiale des Sternes arctiques n'a été que très peu captée par le réseau de télémétrie, ce qui laisse croire que cette espèce n'utilise pas de sites côtiers comme haltes migratoires, mais quitte plutôt les colonies pour se rendre directement à des haltes au large, avant ...
